The present inventionrelates to the art of splicing web rolls and isparticularly adapted for use with a newspaper printing press.

In general, the invention relates to web splic- 5 ing mechanism in.which a movable web roll support isadapted to carry a running roll and afresh roll, with meansfor speeding up the fresh roll prior to splicingandmeans operating in timed relation to the rotation of the fresh rollfor pressing the running web against the fresh roll to make. the spliceand then severing the running web from the expiring roll. The splicingmechanism includes a movable frame on which are carried web pressing andsevering devices, this frame being movable from an inoperative positionto a splicing position, and from the latter position the web pressingand severing devices are operated independently to perform their 7functions. The mechanism as so far described is similar to thatdisclosed in my. copending applications Serial Nos.,591,0'7'7, nowPatent No. 2,048,767 of July 28, 1936, and 686,225., nowiPat ent. No.2,148,094 of February 21, 1939, filed February 5, 1932, and, August 2,19.33, respectively. However the present inventionembodiescertainimprovements over the disclosures in said copending applications. Themechanism for moving the frame from inoperative to splicing position andvice versaincludes a driving motor mounted onthe frame itself. Another.feature of, the present invention is that the several operations of thesplicing cycle are controlled by a multiple switch also mounted on saidframe and driven by said motor. Thus the frame, is a self,-

anism.

Another object of. the present invention is to provide improved meansfor speeding up the fresh roll. i i 40, A further object of the presentinvention is to provide a driving belt for speeding up the fresh roll,such belt being so positioned with respect to the, direction of advanceof said roll that. as the fresh roll is advanced from splicing to run- 5ning position it will be withdrawn bodily from engagement with thedriving belt. One of the drawbacks of roll speeding belts heretoforeencountered has been that in advancing the roll it was dragged along thebelt and by this dragging motion wasoverspeeded, thereby paying out therunning web and causing slack. This difliculty is overcome in thepresent invention by locating the driving belt or belts substantiallyopposite the point toward which the fresh roll is advanced.

Other objects and advantages of my invention will appear in thefollowing description of a preferred embodiment and thereafter thenovelty and. scope of. the invention will be pointed out in the claims.1

Fig. 11 is a diagram of electrical connections.

A portionof the frame of a web press is shown in Fig. 1, namely; anupright and a pair of side beams 36 and 31. The web W is fed to thepressfrom a running roll R carried byone arm of a 5 three armed reel 4E9. Asecond arm of the reel mountsanother roll S to which the web W ispresently to be splicedwhile the third arm carries a third roll X. Theroll R is nearly exhausted and the parts are shown in positionpreparatory to making a splice between the running web W and the web ofthe fresh'roll S.

It will be observed that the web W passes whose other arms 52 areweighted so as to keep the straps taut. The bell-cranks 5I are pivotedon a shaft 53 journalled in suitable bearings 54 carried by the framemembers 36 and 31.

Fresh roll drive The fresh roll S must be speeded up to the same surfacespeed as the web W before the splice is made, and to this end, I providea pair of drive belts 55 which are driven by a pair of pulleys 56, onlyone being visible in the drawings. Each belt is served by three idlers51, 58 and 59. The idlers 51 are rotatably mounted on fixedarms 60, butidlers 58 are rotatably mounted on movable arms 62, secured to anddepending from a shaft 63 journalled in brackets carried by the pressframe. The idlers 59 are rotatably mounted at the extremity of arms 64which are curved to clear the roll S when the beltis driving said roll.These arms are keyed to a shaft 65 which is suitably journalled in theframe members 36 and 371. In order to keep the belts 55 taut, eachmovable arm 62 is spring-pressed away from its opposed fixed arm 6!].Attached to each arm with a swivel connection is a spring rod 51 thatpasses through a poppet 68 swiveled upon the opposite arm 62, while acoil spring 69 mounted on this rod is compressed between the poppet 68and jam nuts 'IEI threaded upon the rod 61. As will be explainedhereinafter the arms I34 are adapted to be swung from the drivingposition, shown in full lines in Fig. 1, to the idle position shown inbroken lines and all the time the belts are kept'taut by the springs 69.

The pulleys 56 are driven through suitable gearing by the main driveshaft I4 of the press. As illustrated in Fig. 1, this gearing comprisesbevel gears I5 providing a driving connection between the shaft !4 andan inclined shaft I6. The

, latter through bevel gears 'I'I drives the shaft I8 on which thepulleys are fixed. By reason of this gearing the belts, 55 are giventhesame surface speed as the web W.

Before a splice is made the leading web edge of roll S is coated withadhesive in the usual manner and the splice isvmade by pressing therunning web against said roll so that it will adhere 'to and pick upsaid edge. Immediately thereafter a knife cuts the web W from theexpiring Iroll R and thereafter the web is fed from the fresh roll S.The running web is pressed against the roll S to make the splice, bybrushes which are'carried in an oscillating brush frame 8| and thisframe also carries the knives for severing the web from the expiringroll. The brush frame normally occupies the position shown in brokenlines in Fig. 1, but is moved to the position shown in full lines,shortly before the splice is made. As .the brush frame moves to thelatter position the belt arms 64 are simultaneously'swung down to theirfull line position to contact the driving belt 5 with the roll S androtate said roll so that its surface speed will be the same as that ofthe running web W.

After the splice has been made the brush frame III and belt arms 64return to their respective idle positions shown in broken lines. Thiscoaction of the two parts is effected by a link 84 which is connected atone end to the brush frame BI and at the. other to a crank arm 85journalled upon the shaft 65. A bifurcated bracket 86 is keyed totheshaft 65 and carries opposed adjusting screws 81 which bear respectivelyagainst opposite sides of the crank arm 85, so that the position of saidcrank arm with respect to the belt arms 64 may be adjusted. The brushframe swings on a shaft 88 as an axis and since the link 84 is connectedto the brush frame below said axis and to the belt arms above their axis65, the driving belt 55 will be moved away from roll S as the brushframe rises and toward said roll as the brush frame descends.

' Reel and roll commutators Details of the reel 4!! are, shown in Fig.2. Journalled in suitable pedestals 90, only one of which is shown, is ashaft 9| of the reel. Only channels facing outwardly, as clearly shownin Fig. 2. A cover plate 96 is fitted over the channels of each arm, thecover plate being securely bolted to the arm. A spindle 91 is mounted inball bearings 98 and 99 carried by the arm and the cover, respectively.The spindle at its inner end is provided with suitable means forengaging the core of the roll of paper mounted thereon. It will beunderstood that at the other end of the reel there is a similarthree-armed spider known as a latching'spider, each arm carrying a chuckadapted to engage the core at the adjacent end of the web roll.

It is necessary to correlate the splicing operations of the machine'withspecific positions of the reel and of the web rolls. Consequently, myinvention provides electrical means for securing the desired synchronismof parts. vPinned to the hub 93 is a flanged sleeve I06 which carriesthe fiber disk I08. Secured to this disk are arcuate commutator stripswhich in general may be designated by thev letter B. 7 These strips areadapted to be engaged by brushes A supported in a fiber block IE9,mounted on a fixed plate I ID. This fixed plate H0 is journalled on thehub and its outer periphery bears against the rim II I of the spiderbody and also fits under a lip H2 of each of the cover plates 96. Theplate IIII is kept from rotating by an arm I I4 bolted thereto and eX--tending upwardly. The upper end of this arm is bifurcated to engage ashaft Hi5 supported by the main frame of the press. Thus, although thereel rotates, the plate I II. is kept from ro-- tating. A cover I I8 maybe provided to protect the fiber block I09 and connections to brushes A.Certain of the commutator strips B are electrically connected to brushesC mounted in a fiber block I20 secured to each cover plate 96 andthesebrushes in turn. engage commutator strips D mounted on a fiber disk I2Isecured to a flanged sleeve I22 keyed to the spindle 9-1. A cover I24 ispreferably fitted over the fiber -block I29 and brushes 0. The relativedisposition of the comthe upper end of the arm IM. The purpose of.

this. gauge will be explained hereinafter.

A motor T is operatively connected through suitable gearing 12'!(Fig. 1) to the shaft Ell, whereby the reel may be rotated to bringsuccessive rolls to splicing and running positions.

The construction of the brush frame III is shown in Figs. 3 to 10inclusive. The brush frame is mounted upon and fixed to the shaft till.This shaft is journalled in bearings formed in brackets I30 and Isl,respectively, secured to the opposite side beams 36 and 31 of the press.The brush frame carries a motor H which operates to swing the frame fromone position to another as will now be explained.

nected by a jaw clutch 35 to a short shaft I31. The latter is suitablyjournaled in a gear box I38 and has a worm I39 fixed thereon. The

outer end of shaft I31 projects from the gear boxand is squared, asshown at Hi0, so that it maybe. turnedmanually when desired by application of a wrench or crank. The worm. I39, as best shown in Fig. 5,drives a Worm wheel IM fixed upon ashaft 142, and fixed to this shaft isa worm I43 which drives a second worm Wheel I44. The worm wheel I44 isfixed upon a crank shaft I45 having a crank arm M6 in which is pivoted apoppet I ll (see also Fig. 6). Through the poppetpasses a spring rod I48which mounts a spring I49 compressed between the poppet and nut I 50.threaded upon the outer end of the rod. A nut I5I bearing againsttheopposite face of the poppet holds the spring in compression. At itsinner end, that is the right hand end, as viewed. in Figs. 5 and 6, thespring rod is bifurcated to cooperate with a pin I52 which connects thespring rod I48 to a shear pin arm I53. This shear pin arm is mounted torotate on the shaft 8.8 and at its lower end is connected by a shear pinI55 to adepending arm 556 of the fixed bracket I30. The pin I52 projectsfrom the spring rod sufficiently to bear against the bracket arm I56,the latter being formed with a depression I 5'! to serve as a seat forthe pin.

It will be evident now that when the motor H is operated, it will rotatethe crank shaft M5 in one direction or the other at greatly reducedspeed owing to the train of worms andworm gears between the motor andsaid crank shaft. If the crank-shaft turns in counter-clockwisedirection, as shown in Fig. 5, the brush frame will be swung outwardlyor toward the left, as viewed in said figure, owing to the thrust of thespring rod I48 and pin I52 against the shear pin arm I53 and the bracketarm I56. Movement of the motor in the opposite direction will tend todraw the brush frame toward the right, as viewed in 1 said figure, sincethe spring rod will then pull upon the shear pin arm which is pinned tothe fixed arm I56. Should the shear him be broken, there will be nothingto prevent the brush frame from moving outwardly or toward the leLEt but.it will be prevented from swinging inwardly by engagement of the pinI52 with the fixed bracket of having the brush arm swing from the dottedto the brush frame ti.

position shown in Fig. 1 to the full line position,

in case the shear pin should break. And the only movement that the brusharm could make under action of gravity would be to swing away from thereel. The purpose of the shear pin is to prevent breakage of vital partsshould the brush arm be swung downward when the fresh roll S is advancedbeyond. the proper position indicated by the gauge I26. i i

In order adjustably to locate the operative position of the brush frame,that is the full line position shown in Fig. 1, I provide an arm I66(Fig. '7) which is fixed to the shaft 88 and carries an adjusting screwIiiI threaded therethrough andadapted to engage a pin I62 mounted in thebracket I3I. .In this way, the lowermost position of the brush frame isfixed, with the spring I49 providing a small amount'of leeway.

The crank-shaft I45 is coupled to shaft I65 which extends to the lefthand end of the brush frame, as shownin Fig. 3, where it is operativelyconnected by miter gears I 55 to the operating shaft I67 of a set of camswitches enclosed in a casing I68. These switches are arranged to closeand open various circuits in predetermined rela- 2 tion to the motion ofthe brush frame, as will be explained more fully hereinafter.

As also shown in Fig. 3, the shaft 83 is provided with a number ofsleeves I'm which freely rotate on the shaft but arekept from endwisemovei nient by collars I'II fixed to said shaft. ()ver these sleevespass the straps lfl, being guided thereby clear of interveningmechanism.

Brush holders A shaft H5 is mounted in bearings I16 secured Mounted onand fixed to this shaft is a set of five brush holders Ill each mountinga brush i'IB. Fixed to the shaft I15 is a set of four arms lllil, onebetween each pair of brush holders, and at the free end of each arm apoppet I8! is pivotaliy mounted. Each poppet is penetrated by a springrod I32 which also passes through a pair of spaced poppets I83 and H14mounted on. the brushframe, one above and the other below thepoppetYItl. A spring IE5 is mounted on an upper extension of the springrod and is compressed between the upper face of the poppet I233 andacollar I36 (Fig. a) secured adjacent the upper extremity of the springrod. Between the lower poppet Ifi l and the poppet IBI, a collar I88 issecured to the spring rod and this collar normally bears against theunder face of the poppet Ifli, thereby urging the shaft I to turncounter-clockwise, as viewed in Fig. '7. A stop collar its secured toand depending from the poppet M3 serves to limit the rise of the poppetI8! and hence limits the angular movement of the shaft Hi5. Normally,however, the brushes aremaintained in their retracted position shown inFig. '2, until release by mechanism which will now be described.

. Bolted to one of the brush holders IT. is a bracket iilflwhich has aprojecting lip it?! normally engaged by a hardened latch Hi2 fixed to anarm I93 freely rotatable on a shaft 5%. The shaft is journaled inbrackets depending from a solenoid box Hi5 which is mounted on the brushframe. The arm I93 is connected at its outer end Thus, when the solenoidis energized by means which will be explained more fully hereinafter,the latch I92 will. be withdrawn from the lip lfii, permitting thesprings I to swing the brushes I'iB forward to the position shown inFig, 8. In

this position, they press the running web against the fresh paper rollto effect a splice.

Knife holders Below the shaft I75 is another shaft 200 mounted inbrackets 20I secured to the brush frame. Mounted on this shaft are fivepairs of knife holders 202. Each holder is bifurcated to receive a knife203 and the knife is clamped in the holder by means of bolts 204. Asshown in Figs. 3 and 4 two torsion springs 205 are mounted on the shaft.Each spring is secured at one end to a collar 20B fixed to the shaft andat the other end engages the adjacent bracket 2!". These springs urgethe shaft to turn clockwise, as viewed in Fig. 7, and tend to move theknives from the position shown in Fig. 7 to that shown in Fig. 8.However, the knives are normally held in the position shown in Fig. 7 bylatch means illustrated in Fig. 9. This latch means comprises an arm 200fixed to the shaft 200 and engaged by a latch 209. This latch isslidable axially in the brush frame, being prevented from turning by aset screw 2I0 engaging a keyway in the latch. An arm 2I I is pivoted ona shaft I94 and is connected by link 212 to the latch 209. The free endof arm 2 is connected by a link 2I4 to the armature 2I5 of a knifereleasing solenoid 2I6, so that when this solenoid is energized thelatch 209 will be retracted from the arm 208, releasing the shaft 200and permitting it to turn under the torsional stress of the springs 205and swing the knives 203 to the position shown in Fig. 8.

Thus, after the brush frame has been brought to the position shown inFig. l, the brushes and knives are swung forward successively undercontrol of the two solenoids to effect the splice and cut the webrespectively. As Will be explained presently the return of the brushframe: to the dotted line position of Fig. 1 serves to reset the brushesand knives to their normal position shown in Fig. 7.

When fractional web rolls are used it is de-: sirable to regulate thepressure of the springs I85 in proportion to the width of the web so asnot to exert too heavy a brush pressure against the web. When a fullwidth web roll is used all four of the springs I85 exert pressure on thebrushes, but, if, for instance, a width roll be used it is desirable tomake one of these springs inoperative. To this end, I provide four hooks220, one for each spring rod, to hold the same in depressed position.These hooks are mounted to turn freely on a shaft 222 and are arrangedto hook over the collars I88. Each hook has a lower extension 223 whichlimits rotary motion hooked to an arm 226 which is fixed to the hook220. This serves the double purpose of looping up the tension strap andof holding the hook in engagement with the collar I88. This generalarrangement is similar to that described in my copending applicationSerial No. 686,225, filed August 2, 1933.

Resetting Mechanism for Brushes and Knives The mechanism for restoringthe brushes and knives --to normal position will now be described.Referring to Fig. 3, it will be observed that the left hand end of theshaft I15 has a retaining collar 230 secured thereto and confining aclutch lever 23I which is loosely mounted on the shaft and cooperateswith a clutch 232 fixed to the shaft ,I'I5. The clutch lever and clutchhave cooperating teeth 233 and 234 (see Fig. '7) which, however, allowsuificient leeway for the brushes to move forward to make a splice. Theclutch lever has an arm 235 which is connected by an adjustable link 236to a stud 231 carried in the bracket I3I. The stud is so related to theshaft 88 on which the brush frame swings that when the brush frame ismoved from the position shown in full lines in Fig. 1 to that shown inbroken lines, the clutch lever 23I will turn the shaft I75 clockwise, asshown in Figs. 7 and 8, and return the brushes from the position shownin Fig. 8 to that shown in Fig. 7. In the latter position the brushesare then held by engagement of the lip I9I with the latch I92.

The same movement is employed to restore the knives from the positionshown in Fig. 8 to that shown in Fig. 7. The clutch lever has an arm 240on which is pivotally mounted a poppet 24I. Fixed to this poppet is arod 242 which passes through a poppet 243 mounted on the end of an arm245 fixed to the shaft 200. The rod is provided at its outer extremitywith a pair of jam nuts 246 which abut the poppet 243 as the brush latchis being reset. As the clutch lever is moved from the position shown inFig. 8 to that shown in Fig. 7, the rod 242 will transmit motion fromarm 240 to arm 245 in such direction as to retract. the knives, and thelatter will then be held in retracted position as the arm 208 (Fig. 9)snaps past the latch 209. This resetting arrangement is similar to thatset forth in my copending application Serial No. 686,225.

It sometimes happens that apparatus of this nature is mounted so thatthere is little clearance between the brush frame and other parts of thepress when the brush frame is inoperative position. Since the operationof this device is essentially automatic, it has been found desirable toprovide a safety switch 250 whose function will be describedhereinafter.As shown particularly in Fig. 10 (Sheet 5) the safety switch is mountednear the free extremity of the brush frame and it has an operatingroller 25I arranged to be operated by an arm 252 fixed to the shaftDepending from and fixed to this shaft are several operating members253, one for each knife. Engagement of any one of these operatingmembers so as to turn the shaft 222 in counter-clockwise direction, asviewed in Fig. 10, will operate the safety switch to open the contactsthereof and thereby stop all motion of the mechanism used in splicing.

The shaft 222 is journalledin the brackets 254 secured to the brushframe (see Fig. 4). A collar 255 is fixed to the shaft; One end of atorsion spring 251, is secured to this collar and the other end engagesthe bracket 254. This serves to urge the shaft 222 in clockwisedirection, as viewed in Fig. 10, so that the safety switch 250 is notoperated erratically. A bar 200 is secured to the brush frame and isformed with notches in which the tension straps 48 may rest when thebrush frame is in operative position. l I V Electrical circuits As shownin Figs. 1 and 11 the reel commutator 13 comprises sets of -concentricarcuate selector strips5B, 4B, 113 and 33 arranged in sectors of 120degrees in extent. Each ofthe outermost strlps"3B is formedwith acentral gap to make commutators D. There are four fixed brushesA whichare individually designated by the same numbers as the selector-stripsonwhich they ride, thus 5A, 4A, IA and 13A; and these brushestareconnected to electric conductor lines 5, A, I' and 3; The strips 313 areitllei's serving extensionst'Bwhemit willbe observed, the lines I and 3are electrically connected. This electrical connection takes @place onlywhen the reel is in any oneof three predetermined angular positions,that is witha fresh rollS inthe position shown in Fig. l, and as willbe-explained hereafter the splicing operation cannot 'take place unlessthe reel is thuspositioned. The rings '5B, 4B and IB of each sector areelectrically connected by brushes 5C, "BC and IC respectively, whichbear on corresponding selector rings 5D, 4D and ID of the rollcommutator-s D. The ring iD of each commutator has an outer projection'SDwhich extends into the path of brush 5C andan inner projection. 4']?that extends into the path of brush "4C. These projections are insulatedfrom the rings 5D andtlD and are angularly separated somewhat less than360deg'rees in the direction of rotation of the rolls (clockwise, asviewed in Fig. 1) so that at each rotation there will be a I momentaryelectrical connection oflines l and 5,

idllowed by momentary connection'of lines I and aiternearly a fullturn'hasbeen madeby theroll. Aswillbe explainedhereinafter the firstelectrical connection controls the release of the brushes t'iii to makethe actual splice and the second connection controls the release of theknives 2 to sever the webi'rom the expiring roll.

At a convenient point 235 a switch is provided for connecting lines i-and '2 to power lines L1 and L2. This switch, known as thepaster switchismanually closed by the operator when henotes that it is abouttime tomake a splice.

Adjacent the-pastel switch is apush-button station 266 containing threeswitches known respectively as the raise? button, lower button, and,

paste button. The first two control respectively the raising andlowering of the brush frame 8| while the last controls the actualpasting of the running web W to the fresh roll S.

-Connected in parallel with the brushhold-in' through [a suitableresistance to one terminal of the. brusHhold-in coil Mfthe otherterminal of whichis connected toline Line 9,as'= has justbeeneXplained-has already beenconnected by armatureeEfito line i l]and-the latter has already been traced throughseries coil lllH ofthebrush coil across lines and 9 is the brush solenoid 199 which is thusenergized, attracting its armature 198 andunlatchin'g the'brushes I78,which thereupon spring forward under impulse of springs I85 to theposition shown in Fig.8 and press the running web against the fresh rollS.v It will be understood that the leading end of the fresh roll hasbeen prepared previously withlsuitable glue and that the said leadingedge has been lightly attached to the body of the fresh roll S'so thatwhen the brushes press the running web against the roll S said leadingedge becomes attached to the running web.

Although it is but a momentary impulse (as brush 5C rides on projection5 D) of the roll commutator that initiates energization of the brushhold-in coil M, the latter remains energi zed by reason of a maintenance'circuit controlled by the reel operation switch. This switch, asexplained above, connects line I to l2 and the latter through thecontact |2L on the armature of the monkey switch is connectedthroughline M to'contact MM. When the brush hold-in coil .is energized,attracting its armature 15M, line H is connected by said armature toline l5 and the energizing circuit is maintained after the connec' 4 sothat when line 4 is momentarily connected to line I as the brush 40 atthe roll commutator rides over projection 4'D of ring ID, this knifehold-in coil N'is energized, attracting its armature 4N. Thisimmediately establishes a main.- taining circuit by connecting line 4through said armature to line i at IN. Simultaneously, the armatureconnects line IE to line [9 at ISN, and line 4 to line 20 at 20N.

The knife solenoid 2 l 6 is connected across lines l8 and 4 in parallelwith the knife hold in coil N so that when said coil isenergized acircuit is completed from line I to line 2 through the knife solenoid,thereby releasing the knives 203 which are swung forward by theirsprings .205 to the position shown in Fig; 8, severing the web from thebutt of the expiring roll R. This takes place when the fresh roll S hasmade almost a. complete turn after the brushes llB have made the splice.

Energization of line 20 causes a signal lamp to be lighted to indicateto an attendant at the conveyor that a splice has been made, so that hewill'be warned to watchfor defective copies. A bv press may have morethan one folder, and since'the same folder may'not be served all thetime, a selector system is provided for lighting a signal; at theparticularconveyor being served by the folder then in service. ,The line.20 runs to a selector switch)" which has two arms so disposed that whenone connects with a contact '20s the other is separatedfrom acontact20b,

, 2,203,607. isconnected to the armature 15M and'the other and viceversaJ Isin'es HA -arid 2013 run from these contacts to signallamps Z'HandZ'lZ respectively and the circuit through either lamp is complete bya permanent connection to line 2. Qbyiously, the selector switch couldbe amplified to take care ofmore two lamps if desired. The lamps remainlightedflas'long as the knife hQld-incoil is energized.

Immediatel-y after the knife hold-in coil N is energized the raise.contactor coil G becomes energized and starts the motor I-lin reversedi-, rection, causing thebrush frame to return to thedotted'lineposition shown in 1. Energiza tion of coilfi isbrought. aboutas follows: It will 7 benoted that the brush hold-in coil M and knifehold-in coil N. continue to be energized and the reel-operation switchremai ns closed. Another of the cam switches known as the up per st opswitch is also closed, having been moved to closed position shortlyafter the brush arm started onthe downward swing. This upper stop switchconnects lines l9 and 2|. As

i has beenlpointed out ab ove, line I9 is connected to line i throughthe reel operation switch. This connection can be traced from the reeloperation switch through line l2 to contact [2L carried by the .armature[3L of the monkey switch, thence through line M to HIM of the brushhold-in switch where contact is being maintained with line 15 and line15 is being held; in contactwith line H] at [9N by the knife hold-incoil N. Now line 2| runs to one terminal ofthe raise C011". tactor coilG, the other terminal of which is connected to line8. As previouslyexplained line 8 is connected through thermal relay F to line 2, so

' that the circuit through coil G is completed.

'runs to the terminal III-I of the motor H and thus line I is connectedto the motor in reverse to the connection previously made. The otherterminal 9H of the motor may be traced to the armature 9E of the lowercontactor, and because the coil E is deenergi zed the contact at IDE isclosed connecting lines 9 and II). Line l0 may be traced through theseries coil Hill to line 2. The motoris thus started in reversedirection and raises the arm to the broken line position shown in Fig.1, where it is stopped by opening of upper stop switch, as will beexplained presently.

The splice having now been completed it is desirable to move the newlyspliced roll S against the straps 48, therefore shortly after the brushframe has started up from the full line position shown in Fig. l-anothercam switch, known as the forward reset switch is automatically closed.This connects lines I and I1. alreadybeen connected by energization ofthe brush hold-in coil M to the line Hi (the connection is actually madeby a contactor HM carried by but insulated from the armature 15M) LineI6 runs to one terminal of the monkey switch coil L, the other terminalof which is connected to line 2. The coil L is thereby energized and itswhile disconnecting lines i2 and M at ML,

The latter has The original maintaining circuit of the brush hold-incoil M was as follows: From line I through reel operation switch to linel2 thence through contactor l2L at the monkey switch to attest? switchcoilL is energized and breaks the contact at IZL. However, in themeantime, another maintaining circuit was established by energization ofthe raise contactor coil G, as follows: From line I at lG to armatureHG, contact IQG, line I9, contact IQN, to line I5, thence through coil Mas described above. I-Ience energization of the brush hold in coil is nolonger dependent position of the monkey switch armature, but iscontrolled by the raise contactor, while the knife hold-in coil Nremains energized as long as the coil M maintains contactbetween linesIt and 2.

Line is may betraced to reel control box 215 where it is connected toline i, while line 22 runs to one terminal 22E of forward contactor coilP, the other terminal of which is connected to line The coil P is thusenergized,attracting Y its armature 23F. The latter ispivotedintermediate its ends so that while it connects line I to a line 23 atif, it also disconnects line 23 from line 2 at 2P. Line 23 runs to brush23T of the nected by a line 24 to line 2.

branch of line 2. iormally connected at contact 2P to the armaturereelmotor T, the other brush 2 3T being con- 23F but has now beendisconnected therefrom by l and thence to line 2.

G breaks the maintaining circuit of the brush attraction of coil P.Since the field coil ITof themotor T is connectedacross lines I and 2the motorT will be operated in forward direction and will advance thereel in counterclockwise directions, as viewed in Fig. Lpressing thenewly spliced roll S against the tension straps 43. This forwardmovement of the reel continues during the upward travel of the brushframe until the forward reset switch opens automatically, disconnectinglines I and H, thereby deenergizing the monkey switch coil L,disconnecting lines It and 22 consequently deenergizing coil .P and reelmotor T and causing the reel to come to rest with freshly spliced roll Sin proper position against the tension straps.

The brush frame 8! and belt arms E i are stopped in the dotted linepositions shown in Fig. l by automatic opening of the upper stop switch,which disconnects lines I9 and 2I, deenergizing the raise contactor coilG, and stopping motor H. The maintaining circuit of the coil G,

as explained above, includes this upper stop switch connecting lines Itand: H, I9 being .connected by energization of coil G'to line i at itsand line 2i being traced through'coil G to line 8 This dropping out ofcoil hold-in coil M by disconnecting lines I and lil at IG and I'QG, andas soon as coil M is deenerglzed the connection between lines 2 and i8is broken at 2M, thereby deenergizing the knife hold-in coil N. i

For the purpose of testing, a raise button is provided in station 26%for connecting lines I and it} and thereby operating the motor H toraise the brush frame 3| without the necessity of operating the brushesand knives.

A control station 278 is provided for. manual control of the reel motorT, a forward switch I and a reverse switch are mounted at this stai 22,coil P, to line 2.

This connection The reel safety switch is closed only when the brushframe is inthe elevated position shown in broken lines in Fig. 1. Sothat manual operation of the reel motor is prevented at all other times.When the forward switch is closed, the following circuits are completed:From line I through line I3, reel safety switch, line 25, forwardswitch, line Coil P attracts its armature ZSP'breaking the contactbetween lines 23 and 2 at ESP and closinga contact at IP between lines Iandft, thereby supplying current from line I to brushHTof theinotor, theother brush NT being coiinect'edthrough line 24 and contact 2V to line'2. When the reverse switch is closed the following circuits are closed.From line i, through line it, reel safety switch, line 25, reverseswitch, line '26, coil V to line 2. Coil V attracts its armature 2 ;V,breakingthe Contact between lines 24 and 2 at 2V and closings. contactat IV between lines I and 26, thereby supplying current from line I tobrush 2 iT, while brush 2.3T is connected through line 23 and contact 2?to line 2.

The safety switch 2% may be connected in series with line I below thefuses in the paste-r switch so that all feeds to line I must passthrough this safety switch. Hence, opening of the safety switch willcause all moving parts of the mechanism to stop, thereby preventinginjury or damage.

Operation The following is a brief description of a cycle of operations:

To prepare for a splice the leading edge of the web on roll S is treatedwith glue in the usual manner. The operator then manipulates the forwardand reverse switches to turn the reel until the periphery thereof isalined with the gauge I28, as shown in Fig. 1, When the depletion ofroll R. indicates that it is about time to make a splice, the operatorcloses the pastor switch to energize lines I and .2 and depresses thelower button. If the reel commutator is substantially in the positionshown in Figs, 1 and 11 the lower contactor coil IE will be energized,supplying current from line I to brush 911 of the brush frame motor H.The other brush IIH being connected through the armature of the. raisecontactor G. to the series the belt arms 59 are lowered to the full lineposition shown in Fig. 1 becauseof their mechanical connection to thebrush frame. The driving belts 55 are thus partially wrapped about theroll S and start the roll to rotating until its peripheral speed issubstantially the same as the surface speed of the running web W. Thedescent of the brush frame and the driving belts is arrested byautomatic opening. of the cam switch marked lower stop.

Everything being now ready for a splice the operator depresses thebutton marked paste and two momentary contacts are closed by thecommutator D. The firsttakes place when brush 5C rides over contactfiDand the second when brush 4C rides over contact 4D. The first contactenergizes brush solenoid I95 releasing the brushes I18 so that theyspring forward under impulse of springs I85 and press the running web Wagainst the fresh roll S. The parts are so timed by the commutator Dthat the web W is pressed against the roll S just as the leading edge ofthe roll is about to pass under the brushes. Before roll S has made afull turn the second contact closed by self-established maintainingcircuits.

Since the solenoids are in parallel with their holdin coils they alsoremain energized and at the same time a lamp signal 21! or 212 undercontrol of the selector switch 2'10, warns an operative at a conveyorstation that a splice is coming through.

When the knife hold-in contactor is energized coil G of the raisecontactor is energized, re-

starting the brush frame motor H but in reverse and the brush frame ismoved upwardly to the dotted line position of Fig. 1. At the same timethe belt arms 64 rise to their dotted lineposition in the same figure.The brush frame motor is stopped at the limit of its upward stroke bythe automatic opening of the upper stop switch which interrupts thecircuit of raise contactor coil G.

This breaks the maintaining circuits of the knife hold-in and brushhold-in coils At the same time link 236 acting on clutch arm 23|restores the brushes and knives to their normal positions in which theyare held by their latches I92 and 209, respectively, now released by thesolenoids I99 and 2H5.

Shortly after the brush frame has started on its upward stroke the reelmotor T is automatical- 1y operated to turn the reel so that the freshlyspliced roll will bear against the straps 48.v This movement starts asthe result of the automatic closing of the forward resetswitch andbegins while the belts 55 are still in contact with roll S. Heretofore,when the roll was moved while in contact with a driving belt there wasan increase in the peripheral speed of the roll owing to the fact thatit was dragged along the belt, thereby producing slack in the runningweb. In the present case, this difliculty is avoided by locating thedriving belt on the opposite side of the roll from the splicing point,so that advance of the roll toward such point will merelywithdraw theroll bodily from the belt without dragging it along the belt.

Closure of the forward reset switch energizes the monkey switch L, whichenergizes the forward contactor coil P and thereby starts the reel motorTin such direction as to turn the reel in counterclockwise direction, asviewed in Fig. 1. The reel continues to turn until the forward resetswitch is automatically opened, breaking the circuit through coil L andthereby deenergizing coil P and motor T. The roll S is thus brought to aposition in which its rotation is properly braked by the straps 48. Thecycle of operations is brought to completion when the brush arm isstopped in its raised position by the automatic opening of the upperstop switch, as described above, and the control equipment is then readyfor another cycle as soon as the'next splice is demanded.

It will be noted that since the brush frame mounts its own motor and camswitches, said frame is a complete self-contained unit which may beapplied as a unit to an existing press or be replaced with another unitin case of need. It will be noted further that the gauge I26 always liesnear the edge of the web roll regardless of any shift of the roll forside register onin cases where short rolls are used-since this gaugemoves with the spider 94 which carries one end of the roll.

While I have described a preferred embodiment of my invention it will beunderstood that this is to be taken as illustrative and not limitativeof my invention and that I reserve the right to make various changes inform, construction and arrangement of parts without departing from thespirit and scope of my invention as pointed out in the following claims.
